y Application filed February 2, 1912. Serial No. 675,621.

To all wzomz'zI may concern Be 1t known that l, Lnoronn MAMnoURG, a.citizen of the Umted States, residing at 'Columbus, Franklin county,Ohio, have invented certain new and useful, Improvements inNursing-Bottles, of which the following is d specification." L

This invention pertains vtoimprovements1n nursing bottles having bottomseals, the 1mproyements being designed to facilitate the eilicient andsanitary sealing of thebase of the bottle, to facilitate'lthe unsettlingof the bottle, and to prevent undesired rollin@ of the bottle, and theimprovements "will` be readily understood from the' :tolloryingdescription teken in connection with the accompanying drawing in WhichrlFigure l is a side elevation of a nursing bottle exemplify/ing mypresent improveniente: Fig. 2 a vertical diametrical section of thebottle proper: Fig. 3 avertical diametricel section of the bottoni capand venttube: Fig. et is a plan ofthe' bottoni cap and vent-tube: andFig. 5 a vertical diametrical section, on a much enlarged' scale,through a portion of the sealing joint between the bottle proper and thebottom cap.

In the drawing zl, indicates the bottle 1noper,.the same beingpreferablycircular in plan: Q, the nipple on the mouth of the bottle: 8, anexternally threaded boss projecting concentrically from the base of thebottle: it, a fiat annular shoulder surrounding the threaded boss: 5, a!threaded nietellic ,cap adapted to be vscrewed upon the threaded boss ofthe bottle: 6, a dat flange forming the rim of the cap: "I, anopenbottomed vent-tube projecting from the oep up into'theV` bottle to apoint near the neck` of the bottle: 8, a small vent-ing aperture in theupper end of the vent-tube: 9,21 gasket, of elastic Flange 6 of the capand the latannular shoulder 4 of the bottle, the thickness of thisgasket being such that the threaded boss of the bettle cannot bottom inthe oep: l0, lugs riphery of the cap: and ll, a large opening throughthe threaded boss of the bottle.`

The opening 1l through the threaded.'

bese of the lbottle is of large size, and the bore or" the base'cf thebottldebove the material, disposed bet-Ween the itatv ving, an externalscrew-thread surroun projecting outwardly from the A pe-' bottom of thebottle, joins the bore of the opening -ll by -a contour contractinginwardly Without any outward growing of the base of the bore of thebottle. By this construction, taken in connection with the mouth of thebottle, the bottle may be readily cleaned by passing 'Water freelythrough it, the' inwall of the bottle being free from groovesorrecesses. The gasket, being compressed between the bottle-shoulder andflange 6 of the cap, effects a. sealing between thecap and the bottleand is as far as pos- Sililerenioied from the contents of the hottle,thus avoiding, as far as possible, any de-, terioratingA eii'ect of thecontents of the bottle uponthe gasket, or contaminatinginfluence of thematerial ot the gasket upon the contents ot' the bottle. When the cap,together with the vent-tube carried by it, is unscrewed'and removed fromthe bottle, the gasket is exposed upon the exterior or the threaded besewhere it may be l readily cleaned, and, if need be, the gasket may bereadily removed from the threaded base for more perfect cleaning or forreplacement in case of damage. The lugs l0, oi' which there may be anydesired number, facilitate the screwing' and unseren/'ing or the csp endAprevent undesired rollingl ot 'thebottle upon a dat surface.

The vent tube Z integrally formed With the cap 5 is of quite largediameter so that it may be easily cleaned 'Jy means of abrush. or swabinserted from the outer end. This cleaning is not possible in cesesWhere ventv tubes ot' small diameter are provided. The sheet-metalconstruction of the cap and tube permit the tubo to be made of amplediameter and sufiicient strength. The relatively large tube terminatesin 'en inwardly tapered portion provided with s relatively smallventop'ening.

ln a nursing bottle or the like, the coin-n gage the bottle thread, anoutwardly eX-' tending flange et the inward end of seid lee 'threlzuh1said cap Harige being opposed to said bottle shoulder, said closure alsohaving an ixitgrallyformed tube of relatively large diameter extendinWithin the bottle and i terminatiiifr in n re atively small vent open-111g, said cosure also being provided at the outward end of itsscrew-threaded portion fvfvith one. olf-miope lateral projections toprovide n fastening grip :m11 prevent rolling, and a gasket between th@closure Bange and 10 the bottle shoulder.l
